Abstract
Methods, systems and apparatuses can be used to detect and prevent invalid or unwanted pulses. In various implementations, pulse information received from a telephony device can be used to identify a duration associated with the pulse. Based upon the duration, a determination can be made whether the pulse is invalid.
